Hi Will,
Since you didn't indicate your (narrower) definition I post one here:
https://en.wikipedia.org/wiki/Object-oriented_design
From this definition I would say that most of the OOD options are open for use. However, to me the model is the code and the code is the model. So I wouldn't put a lot of emphasis on UML modeling, except if it is used simply as a communication tool. Probably the things that separate DDD from OOD in general is DDD's linguistic motivations. With DDD we purposely separate models by the linguistic differences. Even if the same terms are used in both models, they will probably have slightly or vastly different means. You separate model "languages" with Bounded Contexts.
Best,
Vaughn
